Kindred Polarity

Twin Contacts adds a second crate and opposite goal. Aim in place with a visible ray before pushing or pulling; the alternate route uses both polarities and deliberate re-aiming.

Walk to aim; attract or repel the first crate along your facing direction. Crates move one square if unobstructed. Place it on ◎.

Tap or click the controls. Keyboard: Tab and Enter/Space operate every button; arrows/WASD move where available, R restarts, Z undoes calm puzzles.

Mistakes remain revisable. Unlimited undo and restart recover deadlocks.
